In my opinion this is an absolutely critical step, especial early on when you're optimizing gates, vents, etc... The casting software simulations have come a HUGE way since they first came out, but nothing replaced real world testing and verification.

It's not harder to weld? It requires some adjustments, but lots of cast aluminum things get welded, like our cast endtanks to our intercooler cores We make three different kinds of headers that use a cast collector section as well.
